Validation of the Revised Atlanta Criteria in determining the severity of acute pancreatitis.

BACKGROUND/AIM: Determining the severity of acute pancreatitis (AP) is crucial for patient management. The aim of our study was to assess the accuracy and limitations of the Revised Atlanta Criteria (RAC) in determining the severity of AP. MATERIALS AND METHODS: The study was retrospectively conducted on AP patients admitted to the Gastroenterology Department of Sakarya University Faculty of Medicine. The severity, morphology and local complications of AP were evaluated according to the RAC. Laboratory parameters, clinical scores predicting disease severity and Computer Tomography Severity Index scores were assessed. RESULTS: The study group included 113 patients. Ninety-eight (86.7%) had interstitial edematous, and 15 (13.3%) had necrotizing pancreatitis. AP pancreatitis was mild in 69 (61.1%), moderate in 33 (29.2%), and severe in 11 (9.7%). Compared to the moderate group, patients in the severe group had a higher hematocrit, creatinine, SIRS and BISAP scores at admission and more length of hospital stay, more ICU requirements, and higher mortality rates ( P  < 0.05). Eleven patients had single or multiple persistent organ failure (POF). The mortality rate of patients who developed early POF (n = 6) was higher compared to the group of patients who developed late POF (n = 2) (83.3% and 40%, respectively). CONCLUSION: Severity assessment using the RAC in patients with AP is consistent with laboratory parameters and scoring systems predicting severity. Severe pancreatitis cases who develop early POF may be classified separately.

The evaluation of nailfold videocapillaroscopy findings in patients with type 2 diabetes with and without diabetic retinopathy.

OBJECTIVE: Diabetes mellitus (DM) is a chronic hyperglycemic state and is associated with microvascular structural alterations. This study aimed to investigate the diameters of capillary loops and morphostructural changes using nailfold video capillaroscopy (NVC) in patients with type 2 DM with and without diabetic retinopathy (DR). METHODS: This cross-sectional, single-center study was conducted in patients with type 2 DM who were followed in outpatient clinics of ophthalmology and internal medicine. General demographic data were collected from patients. An ophthalmologist examined all patients in terms of DR. A rheumatologist blinded to the clinical data performed NVC. The diameters of apical, arterial, and venous loop of capillaries were measured, and the microvascular changes of capillaries were scored. RESULTS: In this study, 44 patients with type 2 DM with DR (47.7% males) and 20 patients with type 2 DM without DR (55% males) were included. In our study, patients with type 2 DM with DR had more frequent capillary hemorrhage, more frequent ectasia, more frequent giant capillary, and more frequent neo-angiogenesis than patients with type 2 DM without DR. However, these findings were not statistically significant. CONCLUSION: Further controlled studies with large sample size are needed to determine the characteristic NVC findings of DR in patients with type 2 DM.

Endocan, TGF-beta, and ADMA as Risk Factors for Endothelial Dysfunction and Possible Vascular Disease in Patients with Subclinical Hypothyroidism.

PURPOSE: Although the relationship between atherosclerosis and overt hypothyroidism has been confirmed, it remains controversial in cases of subclinical hypothyroidism. Higher TSH and similar T4 suggest differences in set-points or differences due to diagnostic limitations regarding subclinical hypothyroidism. Endothelial dysfunction (ED) is a marker rather than a precursor of cardiovascular disease. Asymmetric dimethylarginine (ADMA) and endocan are known as novel markers of ED in various diseases. Transforming growth factor-beta (TGF-ß) has a protective role against autoimmune diseases such as thyroiditis. This study aimed to determine the relationships between serum ADMA, endocan, TGF-ß, and the high-sensitivity C-reactive protein (hs-CRP) levels, a proven indicator of ED, in patients with SH. METHODS: Thirty-five patients with SH and 21 age- and sex-matched euthyroid subjects were included in the study. The levels of TSH, FT4, lipid parameters, endocan, ADMA, TGF-ß, and hs-CRP were measured. RESULTS: No significant differences in age or sex were found between the patient and control groups (p=0.294 and 0.881, respectively). Mean TSH level was higher in the patient group (p=0.005), whereas mean fT4 level was similar in two groups (p=0.455). The average hs-CRP, endocan, TGF-ß l level in the patient group was higher than control group (p=0.001; P=0.012; P=0.025; P<0.01 respectively). A positive correlation was found between the endocan and ADMA levels (r=0.760, p=0.000). ADMA levels also were positively correlated with hs-CRP. Both the TSH and low-density lipoprotein cholesterol (LDL-C) levels were positively correlated with the hs-CRP level. CONCLUSIONS: Subclinical hypothyroidism is associated with increased levels of serum endocan, ADMA, and TGF-ß, which are new markers for ED. In particular, ADMA was correlated with both endocan and hs-CRP levels. These findings are suggestive for increased risk of ED and subsequent development of atherosclerosis in patients with SH.
